CAR-TRUCK.

Specification of Letters Patent.

Patented Dec. i9, 1916.

Application filed October 25, 1916. Serial N o. 127,509.

To all 'whom t may concern.'

13e it known that I, RALPH E. VVILDER, a citizen of the United States,residing in the city of Johnstown, in the county of Cambria and State ofPennsylvania, havevinvented certain new and useful Improvements inCarffrucks; and I do hereby declare the following to be` a full, clear,and exact description of the invention, such as will enable othersskilled in the a-rt to which it appertains to make and use the same.

My invention relates to car trucks with partlcular reference to thoseadapted for supporting heavy cars, and to the construction of the truckcolumns which I make of pressed steel', of shapes such as to well resistthe stresses to which they will be subjected, and formed integrallytherewith is an inwardly extending portion adapted to directly receivethe brake beam' stirrup or hanger, thus simplifying the construction andreducing the number. of parts thereof.

l I also provide a reinforcement for the lower portion of the arch baror similar' member,

to prevent its bending or fleXure in use, and

I further stiti'en the structure vertically by the. use of pipe thimblessurrounding .the bolts, the ends of which abut against the innersurfaces of the end flanges of my pressed steel column guides.

Having thus given a general descriptio of myinvention, I will now, inorder to make the matter more clear, refer to the anneXed sheet ofdrawings forming part of this specification and in which like charactersof reference designate like; parts.

Figure 1 is a side elevation of my improved truck; Fig. 2 is a top planof the side frame with the wheels and journal boxes removed for the sakeof clearness of illustration; Fig. 3 is a vertical cross sectionalelevaton taken on the line III- III of Fig. 2; Fig. 4 is a sideelevation of a portion of the column guide shown in Fig. 3; Fig. 5 is averticalcross sectional elevation of the column guides illustrated inFigs. 3 and 4 on the line V,-V of Fig. 6; Fig. 6 is a sectional plantaken on the line VI-VI of Fig. 4; Fig. 7 is a cross sectional plantaken on the lineVII-VII oi4 Fig. 5; and Fig. 8 is a detailedlongitudinal vertical sectional clevation of the parts adjacent one ofthe'column bolts.

Referring now to the various characters of reference on the drawings: lis the upper arch bar, 2 the lower arch bar, the ends of which'areturned up and abut against the ends of the upper arch bar, 3 is alreinforcing member secured to the *lower arch bar by rivets countersunkon top, as shown; l is the lower tie bar, 5 are the journal boxes ofusual construction, 6 is the spring plank shown as of pressed steelsecured to the bottom arch bar and to the column guides by rivets; 7indicates my pressed steel column guides generally, 8 are the columnbolts, 9 are pipe thimbles made preferably of heavy wrought iron orsteel which surround the column bolts with their ends abutting againstthe insides of the'horizontal flanges of the truck columns in order tostii'en the structure; 10 is an inwardly extending porf ltion of theintegral column guide adapted space for introducing the bolster intoposition, after which the bolster is moved upwardly into contact withthe guide portions 10, l2 is the upper horizontal flange of the columnguide adapted to be secured against the lower surface of the upper archbar 1,

13 is the lower horizontal fiange of the column guide adapted to besecured against the upper surface of the stiiening member 3, asillustrated; 14 is an integral projection eX- tending diagonally inwardfrom the body of the column guide, provided with web portions 15 and 16,which are provided with holes, -as illustrated, and so located andadapted as to form a direct support for the brake beam stirrup or hanger17, which is pivotally secured thereto by means of the bolt 18, whilethe usual springs are illustrated as19 and the bolster as 20. `By

umn guides which are integrally formed .of

pressed steel and oi' a strength sul'licient to stand the' stresses towhich they are subjected, and of quality such that they are better thana casting or a column guide made of more pieces, my column guide and thebrake hanger being formed integral.

On account of the necessary width of a truck frame of this character,the' load applied thereto from the springs is transmitted to the lowercentral portion of the lower arch bar and would tend to bend or ieX it,but `my stiii'ener 3 is used for the purpose of strengthening the lowerarch bar to prevent this.

Although I have described and illustrated my invention in considerabledetail, I do not Wish to be limited to the exact and specific detailsthereof as shown and described, but

5 may use such modifications in, substitutions for, or equivalentsthereof, as are embraced Within the scope of my invention, or as uointedout in the claims.

Having thus described my invention, what 19 I claim and desire to secureby Letters Petent is l. An integrally formed column guide of pressedsteel comprising top and bottom 'flanges adapted to tit within theopening of i', a truck frame, the upper part of which extends toWa-rdthe bolster to form :i bolster guide, said truck column being providedwith :in integral inwardly extending portion adapted to directly supporte brake beam hanger pivotally secured thereto.

2. An integrally. formed pressed steel column guide comprising upper andlower flange portions adapted to tit Within the opening between thetruck arch bars, the upper portion adapted to contact with the bolsterand the lower portion not adapted to Contact with the bolster, a pair ofwebs eX- tending vertically between the arch bars, an imvzirdlyprojecting portion comprising n web und flanges, the flanges beingperforated und edn )ted to su )ort e brake beam hander:

In testimony whereof I hereunto etIiX my signature.

RALPH WILDER.
